Which experiment shows that the wavelength of light is smaller than that of sound?
Correct answer: A. Diffraction
- A. Diffraction
- B. Polarization
- C. Interference
- D. Reflection
Explanation
Explanation: Diffraction is the phenomenon where waves bend around obstacles or spread when passing through an aperture. The extent of diffraction is related to the wavelength of the waves. When light undergoes diffraction, it exhibits more significant bending or spreading than sound due to the smaller wavelength of light compared to sound.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
